GL1800 front brake drag

Post by Chowdher » Thu Jul 13, 2017 9:21 am



Hi all,

I have an 07 GL1800 with dragging front brakes. With wheel suspended, I get about 1/4 revolution. After a short ride, with no brake use, the rotors are almost too hot to touch. The rear tire spins freely, and the brake recall has been done. The drag did not disappear with opening the bleed screws, so I concluded it was an issue with the caliper. As well, the right caliper seems worse than the left.

So, I rebuilt both calipers (new seals and pistons) and cleaned the m/c - the problem persists...

I cant see how - but can one screw up a caliper rebuild??

Any guidance would be appreciated.

John

When you rebuilt the calipers, did you scrape out the seal grooves with a dental pic? Any hard deposits left in the grooves will put pressure on the seals and thus the pistons won't retract properly.

@newday777 - yes, I used a scriber to clean the crap out of the grooves...

When you bled the brakes did you follow the repair manual specified sequence?

There have been several brake recalls on the 1800. Did you take it in for the latest recall
(1 1/2 yr) for them to replace the rear master cylinder and the secondary master cylinder on the left fork?

Did you clean the master cylinder and make sure that the relief hole is clear? The brake recalls have all been related to the rear brakes. They won't do anything with the front unless you request it. And don't forget the clutch system too. All of those fluids should be changed every TWO years... No matter how many or few miles you drive.

You sure they were very nice a clean? I normally pump my brakes until the pistons are very very far out then its brake cleaner and a toothbrush...
